a hookah question?

What is happening my breathren, i hope you are all enjoying your weekends? I have a quick question, normally i just throw mah green into the bowl and light up, but my friend showed me these burning coal things\. They have a bunch of different flavors, but my question is, can i put the weed into the head(bowl for those who dont know much hookah) put some tinfoil over it till i get a big screen and put the coal on top, will it burn hot enough to aloow the weed to be smoked like it does tobacco or nay?

I've done this before, works great. Works allot like a vaporizer if you get the right size cole (you want the small ones) As far as the tinfoil is concerned, be sure to visit your local hookah bar and ask what they use and where you can get it. Thy should have a special kind of tinfoil that doesn't have the negative health effects.
